Answer:
Width = 3.75 feet
Length = 9.75 feet
Step-by-step explanation:
Given:
Length of fencing = 27 feet
Find:
Dimensions of the garden
Computation:
Assume
Width = x
So,
Length = x + 6
2(L+B) = Perimeter
2(x + x + 6) = 27
2(2x + 6) = 27
4x + 12 = 27
4x = 15
x = 3.75
Width = 3.75 feet
Length = 3.75 + 6 = 9.75 feet

A pack of cinnamon scented pencils sell for $4.00 what is the sales tax rate if the total cost of the pencils is $4.32
Answer:
8%
Step-by-step explanation:
To get the answer we can use proportion. We know that 4$ its 100% and 4.32 its 100% + taxes.
4$ ---------- 100%
4.32 -------- x
cross multiply now
4x=4.32*100%
4x=432% /:4
x=108%
We know that 4.32 its 100% + taxes=108% so to get taxes we have to subtract 108-100.
108%-100%=8% - its the answer.
Answer:
8%
Step-by-step explanation:
$4 represents the sale price
4.32 - 4 =$ .32 represents the sale tax
Tax rate is the percentage $ .32 out of $4.
4 is 100%
.32 is x%
Cross multiply to find x, and divide by 4
x= (.32·100) / 4
x = 8
The tax rate is 8%.

An angle measures 66° more than the measure of its complementary angle what is the measure of each angle
Answer:
The measures of the two angles are 12° and 78°
Step-by-step explanation:
Let us explain what is the complementary angles
Two angles are complementary if the sum of their measures is 90°
Example:
If m∠x + m∠y = 90°, then
∠x and ∠y are complementary angles
Let us solve the question
Assume that the measure of one of the complementary angle is x°
∵ The measure of its complementary is 66° more than it
∴ The measure of its complementary = x + 66
∵ The sum of the measures of the complementary angles is 90°
∴ x + 66 + x = 90
→ Add the like terms in the left side
∴ 2x + 66 = 90
→ Subtract 66 from both sides
∴ 2x + 66 - 66 = 90 - 66
∴ 2x = 24
→ Divide both sides by 2
∴ [tex]\frac{2x}{2}=\frac{24}{2}[/tex]
∴ x = 12°
→ Substitute the value of x in the second angle to find x
∵ The measure of the other angle = 12 + 66
∴ The measure of the other angle = 78°
∴ The measures of the two angles are 12° and 78°
Answer:
12 and 78
Step-by-step explanation:
Let us explain what is the complementary angles
Two angles are complementary if the sum of their measures is 90°
Example:
If m∠x + m∠y = 90°, then
∠x and ∠y are complementary angles
Let us solve the question
Assume that the measure of one of the complementary angle is x°
∵ The measure of its complementary is 66° more than it
∴ The measure of its complementary = x + 66
∵ The sum of the measures of the complementary angles is 90°
∴ x + 66 + x = 90
→ Add the like terms in the left side
∴ 2x + 66 = 90
→ Subtract 66 from both sides
∴ 2x + 66 - 66 = 90 - 66
∴ 2x = 24
→ Divide both sides by 2
∴
∴ x = 12°
→ Substitute the value of x in the second angle to find x
∵ The measure of the other angle = 12 + 66
∴ The measure of the other angle = 78°
∴ The measures of the two angles are 12° and 78°

Answer:The first is a function but the second isn’t.
Step-by-step explanation: The numbers in the first circle (domain) should only point to one number in the second circle (range). Meaning the domain should only have one arrow for it to be a function. Therefore the first problem is a function, but the second problem is not. For

Jane paid $40 for an item after she received a 20% discount. Jane's friend says this means that the original price of the item was $48.
Answer: she is wrong
Answer: her friend was wrong
Step-by-step explanation:
Jane’s friend found that 20% of 40 is 8. Then she added $8 to the sale price: 40 + 8 = 48. Then she determined that the original amount was $48.
b. Is her friend correct? Why or why not?
Jane’s friend was incorrect. Because Jane saved 20%, she paid 80% of the original amount, so that means that 40 is 80% of the original amount.

y = 1/2x - 2 Dave said his table
is correct. Bonnie said her
table is correct. Who is
correct? Explain your answer.
ILL PUT YOU AS BRAINLIEST
Answer:
Both tables are correct.
Step-by-step explanation:
The equation given is y = [tex]\frac{1}{2}[/tex] x - 2. When you replace x with each value given from Dave's table, the y values will be those given.
-4 = [tex]\frac{1}{2}[/tex] (-4) - 2
-3 = [tex]\frac{1}{2}[/tex] (-2) - 2
-2 = [tex]\frac{1}{2}[/tex] (0) - 2
-1 = [tex]\frac{1}{2}[/tex] (2) - 2
When you use the values given in Bonnie's table, the equations are also all true.
0 = [tex]\frac{1}{2}[/tex] (4) - 2
2 = [tex]\frac{1}{2}[/tex] (8) - 2
4 = [tex]\frac{1}{2}[/tex] (12) - 2
6 = [tex]\frac{1}{2}[/tex] (16) - 2

PLEASE HELP ME!!! An equation of the line tangent to the graph of y = 2x+3/3x-2 at the point (1,5) is
Answer: 13x + y = 18
Step-by-step explanation: 13x + y = 18 is equal to y = -13x + 18.
The derivative is y' = -13/3x-2^2.
With the derivative, you get -13 for slope and plug it in to get y - 5 = -13x + 13.
Move it around and you get 13x + y = 18.
Hope this helps!
We want to find the equation of the tangent line to a given point in a given function.
The correct option is B: 13*x + y = 18
So we want to find the equation of the tangent line to the function.
[tex]y = \frac{2x + 3}{3x - 2}[/tex]
at the point (1, 5).
To get the slope of that line, we need to evaluate the derivate of the function in the x-value of the point, the derivate of the function will be:
[tex]y' = \frac{2}{3x - 2} - 3*\frac{2x + 3}{(3x - 2)^2}[/tex]
Now we evaluate this in the x-value of the point, which is x = 1.
[tex]y' = \frac{2}{3*1 - 2} - 3*\frac{2*1 + 3}{(3*1 - 2)^2} = -13[/tex]
Then the line will be something like:
y = -13*x + b
To find the value of b, we use the fact that the line must pass through the point (1, 5). This means that when x = 1, we have y = 5.
Replacing that in the line equation we get:
5 = -13*1 + b
5 + 13 = b
18 = b
Then the equation of the line is:
y = -13*x + 18
Or, rewriting it.
13*x + y = 18
So the correct option is B.

Select the correct answer in each of the following
Answer:
A, A and A
Step-by-step explanation:
Given
y = ax² + bx + c ( a ≠ 0 )
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
The graph here is a maximum, thus a < 0 → A
--------------------------------------------------------------------
The value of c is the y- intercept of the graph ( when x = 0 )
Since the y- intercept is below the x- axis then c < 0 → A
--------------------------------------------------------------------
The solutions to the equation are where the graph crosses the x- axis ( y = 0 )
Since the graph crosses the x- axis to the left of the y- axis, then
both solutions are negative → A

120
steps per minute and that each step is 2.75
2.75
feet long. Which calculation is most reasonable for James to use to find out his walking speed in miles per hour?
Answer:
speed of James is: 3.75 miles/hour.
Step-by-step explanation:
We need to find the speed of James in miles per hour(mi/hr)
we know that 1 mile=5280 feet
James takes 120 steps in 1 minute so he will cover 120×60 steps in 1 hour.
i.e. he takes 7200 steps in 1 hour.
also each step of James=2.75 feet
total distance covered by James in 1 hour=2.75×7200 feet=19800 feet
[tex]19800feet=\frac{19800}{5280} miles=3.65miles[/tex]
hence speed of James= (distance covered by james in 1 hour)/1 hour
speed of James=3.75 miles/hour.

A skydiver was directly above a ferris wheel when he jumped out of the plane. His friend was watching at the landing field and looking up at the airplane at an angle of 50°. The friend’s eyes were 5.5 feet above the ground when looking up, and he was standing 1050 ft from the ferris wheel. How high was the skydiver when he jumped?
Using the slope concept, it is found that the skydiver has at a height of 1257 ft when he jumped.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem:
The vertical change is of x - 5.5, in which x is the skydiver's height.The horizontal change is of 1050 ft.The angle is of 50º.Hence:
[tex]\tan{50^\circ} = \frac{x - 5.5}{1050}[/tex]
[tex]x - 5.5 = 1.19175359259 \times 1050[/tex]
[tex]x = 1257[/tex]
The skydiver has at a height of 1257 ft when he jumped.
